Backlash after Bernie supporter's #DemocraticWhore comment

Bernie Sanders is doing some political damage control on Thursday after a supporter used the phrase "corporate Democratic whores" ahead of his speech at a campaign rally in New York. Dr. Paul Song, who is an oncologist and an outspoken advocate for single-payer health care, received applause from Bernie’s supporters, but outrage from Hillary supporters. "Medicare for all will never happen if we continue to elect corporate Democratic whores, who are beholden to Big Pharma and the private-insurance industry instead of us," Song said.

Sanders' campaign took to Twitter on Thursday to denounce the comments made by Song. "I am very sorry for using the term 'whore' to refer to some in congress who are beholden to corporations and not us. It was insensitive," Sanders tweeted.

Dr. Song's comment was inappropriate and insensitive. There's no room for language like that in our political discourse.

Song later apologized on Twitter clarifying that he wasn't talking about Hillary Clinton. Instead, he insisted, it was members of Congress, who failed to pass a public option during the debate over the Affordable Care Act that he was calling whores.

“I am very sorry for using the term "whore" to refer to some in congress who are beholden to corporations and not us. It was insensitive,” Song tweeted.
